It should be compatible with GM's cash incentive. Its likely not compatible with other incentives (USAA, Credit Union, etc), as they are typically considered private offers as well.

idk, seems like they are only going to give out $2000 in offers, i was watching the screen as he was puting in the incentives, other offers would go away. if i can get one to print out next month, i will bring it in with me, cant hurt.
